tests AROM of shoulder

pt…
reaches up behind head and touches superior medial angle of opp scapula w/ fingertips (external rotation, abduction)

Q

shoulder arc

A

tests AROM of shoulder

pt aBducts arms to 90 degrees w/ elbows straight, turns palms up, then continues to aBduct until hands are over head

pain –> “painful arc”

Q

Drop arm test
